Title: Improvements in or relating to gas pressure regulating devices
IPC: B67C3/12
Filed: 1951-10-08
Abstract: 702,237. Valves. FARRINGDON WORKS & H. PONTIFEX & SONS, Ltd., and KNOWLES, G. Oct. 8, 1951, No. 23411/51. Class 135 A gas pressure regulating device employed in counter-pressure bottle filling machines for controlling, during a filling operation the exhaust of pressure from bottles through a pressure balancing chamber to regulate the final filling level, comprises a displaceable member, e.g. the diaphragm 4, subjected to the differential action of the gas pressures in the balancing chamber applied via connection 45 to chamber 44, and in the reservoir of liquid to be bottled, applied via connection 43 to chamber 42a, mechanically adjustable means for applying additional pressure to the diaphragm in opposition to the balancing chamber gas pressure and a needle valve 41 displaceable by the diaphragm to control leakage of this pressure. Air pressure from the same source is supplied to both balancing chamber and reservoir, and the spring 18 is adjusted through the worm and pinion 21, 20, screwed spindle 19, and spring abutment shaft 12 splined at 27, 28, to prevent rotation, until it exerts on the diaphragm a pressure equal to the difference in level between the liquid in the reservoir and the liquid in the filled bottle so that a predetermined back pressure is exerted in the balancing chamber and in chamber 44 which stops the rise of liquid in the bottle when the desired level is reached. The angular displacement of the spindle 19 is indicated by an index wheel 29 and by the serration on the worm handle 24 which engages a spring-pressed plunger. The leakage of air from chamber 44 is controlled by a valve face 35 carrying the needle valve engaging an annular seat 36a surrounding the needle valve orifice. The initial position of the seat is adjusted by screwing the shaft 37a in the casing and the position of the needle valve orifice is adjusted by screwing the hollow shaft 39 in the shaft 37a. Specification 702,211, [Group XVII], is referred to.

Abstract: 1441208 Insulated pipeline CONTINENTAL OIL CO 28 May 1974 [2 July 1973] 23520/74 Heading F2P A method of preparing an insulated negative buoyancy flow line comprises positioning a jacket 2 concentrically around a conduit 4 to provide an annulus therebetween, closing one end of the annulus with spacer 6, filling the annulus with an insulating material 18 comprising a mixture of a porous filler 12 of hollow closedcell construction and a settable resin 16 and allowing the resin to set. Porous filler 12 and resin 16 may be delivered into the annulus as a mixture or in that order through probes 10 and 14 passing through a spacer 8 which otherwise closes the other end. Conduit 4 may be of metal, ceramic, cement or plastic. Jacket 2 may be of similar materials but preferably of cement and should add sufficient weight to the flow line to provide it with negative buoyancy when placed in a body of liquid. The insulation material comprises 50-75% of a porous filler of hollow closed-cell construction, e.g. hollow glass or fly ash microspheres or rigid closed-cell foam beads, e.g. of thermosetting resins such as urethane, epoxy, phenolic, urea formaldehyde or silicone or of thermoplastic resins such as polystyrene, vinyl, polyolefin or cellulosic, and 50-25% of a settable resin such as epoxy resin. Jacket 2 is preferably shorter than conduit 4 to enable sections of flow pipe to be connected, the joint being insulated by preformed sections of insulant and jacket.

Abstract: 1473188 Double-walled heat exchanger; cooling of water BOC LINDE REFRIGERATION Ltd 28 May 1975 [28 May 1974] 23642/74 Headings F4H and F4S  A double-walled heat exchanger (e.g. for cooling water) comprises an inner container 4 and an outer container 2 with refrigerant coils 24 therebetween. The water is cooled while in contact with the coils. The interspace between the inner and outer containers is divided by horizontal partitions into chambers 23 which extend around the apparatus. Apertures 26 in the partitions connect the chambers in series for water flow therethrough. In each chamber there is a vertical baffle 30 (illustrated more clearly in Fig. 3, not shown) which acts as an end wall of the chamber forcing the water to pass into the next chamber. The interior of the inner container 4 is. divided by a partition 6. Water to be cooled (e.g. which is circulated from and to a milk cooler or air conditioning plant) passes through pipe 9 into compartment 8; thence it passes through pipe 10 and is pumped at 12 through pipe 14 to the interspace between the containers 4 and 2. It enters the lowest chamber 23 as illustrated in Fig. 3 (not shown), and passes through the chambers in series. From the uppermost chamber, it passes through pipe 16 into a compartment 18. From there it leaves through pipe 20 to be pumped at 21 from the apparatus through pipe 25. There may be interchange of water between the compartments 8 and 18. For example, the partition 6 may serve as a weir or may have an opening therethrough at its base. Refrigerant is supplied to the coils 24 as indicated in Fig. 1 and removed through pipes 27 via a manifold 29. The inner container 4 (i.e. the four inside walls) is removable. Further, end outside wall 28 is detachable permitting the refrigerant coils 24 to be removed en bloc. The apparatus could be used in reverse, i.e. as a condenser in which vapour within the coils is condensed into a liquid by giving up heat to a coolant fluid in the chambers.

Abstract: 865,180. Knitting-machines. SCOTT & WILLIAMS Inc. June 25, 1957 [July 19, 1956], No. 23848/60. Divided out of 865,178. Class 74 (2). To control the size of stitches being formed in a circular machine, the sinker cam means is controlled to modify the sinker wave, by means responsive to sensing means which is, in turn, responsive to the size of stitches produced. A lever 248 controllable by a sinker feeler cam 244 effects pneumatic control of a servomotor which, through linkwork including lever 294, adjusts the position of a cam 298 which, in turn, determines the extent and timing of sinker movement imparted by a swingable cast-off sinker cam 254. The apparatus is rendered effective or ineffective by cams on the main drum which, acting through a rod 286 and lever 282, can project inwardly a slide 276 carrying the lever 294, against the action of a spring 280. The cam 254 is linked to the pivoted centre sinker cam 250 by a pivoted plate 262. The pneumatic means is similar to that described in Specification 865,178. Specifications 753,212,764,694,865,179,865,181 and 865,182 also are referred to.

Title: Improvements in or relating to optical projection apparatus
IPC: G02B15/14
Filed: 1937-09-03
Abstract: 503,600. Optical-projection apparatus. BROWNE, C. O. Sept. 3, 1937, No. 24133. [Class 97 (i)] In optical-projection apparatus wherein the magnification is variable by movement, relatively to a fixed projection lens, of the object support and an image receiving device, the movable members being connected by a linkage so as to maintain the focus, fixed illuminating means is provided in such manner that the intensity of illumination of the image remains constant whatever the magnification; the illuminating means may comprise a fixed light source and a fixed condenser converging the light to a point at or near the projection lens, and this convergence causes the intensity of illumination of the object to increase as the object is moved from the source, thus producing the constancy of illumination of the image. As shown in a television transmitter the lamp house 1, condenser 2, and projection lens 4, are fixed on a rod 10, and produce an image of an object 3 in the object plane of a lens 5 which is movable with a housing 6 and itself produces an image on the screen of a transmission tube in the housing. A rod 11, depending from the holder of the object 3, and the housing 6 are linked by a right-angled lever 14 pivoted at 15 and having slotted arms, the slots being respectively engaged by the rod 11 and by a pin 17 on a member 20 secured to the housing 6. The beam from the condenser is convergent to render constant the illumination of the image, and the linkage ensures, as explained in detail in the Specification, that the image remains in focus. Specification 27777/11, [Class 97 (i)], is referred to.
